We evaluate the export diversification structure of developing countries using a large cross-country panel of detailed exporting activity and constructed world market prices in the context of modern portfolio theory. We find that there are considerable welfare gains from moving towards a more...

The relationship between growth and pollution is studied through a vintage capital model, where new technologies are more environmentally friendly. We find that once the optimal scrapping age of technologies is reached, an economy may achieve two possible cases of sustainable development, one in...

We study how the import of older and more polluting technologies alters the relationship between output and environmental quality in developing countries within a vintage capital framework. Our results show that old technologies prolong the period until which pollution may eventually decrease...

This paper re-examines the existence of an Environmental Kuznets Curve (EKC) across countries using a semi-parametric regression estimator, which places no restrictions on the functional form. Our results using crosscountry panel data on Sulfur and Carbon Dioxide strongly suggest that the...

We investigate how urban concentration and urbanization affect economic growth in developing countries. Using semi-parametric estimation techniques on a cross-country panel of 39 countries for the years 1960-1990 we discover a U-shaped relationship for urban concentration. this suggests the...

We study how the import of older and more polluting technologies alters the relationship between output and environmental quality in developing countries within a vintage capital framework. Our results show that old technologies prolong the period until which pollution may eventually decrease...

We study the coagglomeration of domestic plants and foreign multinationals and the impact of this on domestic plant growth using data for Irish manufacturing. To this end we make use of the index developed by Ellison and Glaeser (1997) and find coagglomeration to be important for a number of...

In a recent paper, [Cabral, L. M. B. and J. Mata, 2003, American Economic Review, <Emphasis Type="Bold">93, 1075–1090] using Portuguese manufacturing data have shown for the first time that the plant size distribution is significantly right-skewed at the early part of the life cycle and then changes to become more...</emphasis>
